Unique namespace

A unique namespace determines the links that get removed if graph collapse happens.

A single merged profile and its corresponding identity graph should represent a single individual (person entity). A single individual is usually represented by CRMIDs and/or Login IDs. The expectation is that no two individuals (CRMIDs) are merged into a single profile or graph.

You must specify which namespaces represent a person entity in Identity Service using the identity optimization algorithm. For example, if a CRM database defines a user account to be associated with a single CRMID and a single email address, then the identity settings for this sandbox would look like:

  • CRMID namespace = unique
  • Email namespace = unique

A namespace that you declare to be unique will automatically be configured to have a maximum limit of one within a given identity graph. For example, if you declare a CRMID namespace as unique, then an identity graph can only have one identity that contains a CRMID namespace. If you do not declare a namespace to be unique, then the graph can contain more than one identity with that namespace.

NOTE
  • Household entity representation (“household graphs”) are not supported at this time.

  • All namespaces that are person identifiers and that are used in the sandbox to generate identity graphs must be marked as a unique namespace. Otherwise, you may see undesirable linking results.
